Guide for owners and naval architects on how and where to submit ship stability information for Martime and Coastguard Agency authorisation.
Stability guidance booklets
These publications give guidance on the format and content of stability information you’ll need to provide for masters so they can assess the stability of a vessel in any condition of loading.
- Stability information booklet - load line vessels
- Stability information book - passenger ships (appendix 10)
- Stability information book - passenger ships (appendix D)
- Stability information book - fishing vessels
Approval of stability
You can check who’ll be responsible for stability approval for your vessel by referring to ‘Approval of stability: authorisations for stability approval by vessel type’. If in doubt contact the Stability Unit for further guidance.
We ask the owner’s naval architect to complete and return a stability approval questionnaire along with the drawings listed, at an early stage in any project.
Stability information submissions
All stability submissions to MCA should be made through your Marine Office surveyor, or sent to the Stability Unit.
